Given below are two statements : Statement I : H₂ O molecules move from the chamber 1 to chamber 2 . Statement II : The osmotic pressure of a solution prepared by dissolving 50 mg of potassium sulphate (molar mass = 174 g/mol) in 2 L of water (at 27° C) is 0.0107 bar. (Given : R = 0.083 dm ^3 bar K ⁻¹ mol ⁻¹ and assume complete dissociation of electrolyte) In the light of the above statements, choose the correct answ

Step-by-step solution

For Statement I: Molarity of the solution in Chamber 1 ( M₁ ) = 18 / 180 100 / 1000 = 1 M Molarity of the solution in Chamber 2 ( M₂ ) = 30 / 180 250 / 1000 = 1/6 1/4 = 0.667 M Since M₁ > M₂ , the solution in Chamber 1 has a higher solute concentration. During osmosis, the solvent (water) moves from the region of lower solute concentration to the region of higher solute concentration across a semi-permeable membrane. Thus, water will move from Chamber 2 to Chamber 1. Statement I is false. For Statement II: The osmo
